Page 10: Introduction
N T R O D U C T I O N The Hafler P1000 is a single rack height, two channel professional power amplifier suitable for use in any situation where a moderately powered compact amplifier is required. The P1000 is particularly attractive for use in broadcast monitoring situations. -

Page 12: Installation
AC LINE The P1000 is capable of operation from either a 115 VAC/60Hz or a 230 VAC/50-60Hz power line. The power line selector switch is located on the rear panel. Check that the switch is set in the correct position before putting the amplifier into service. -
Page 13: Balanced Input
Pin 2 = (+) Pin 3 = (–) Many popular mixers use unbalanced outputs and can be used with the Hafler amplifier. To minimize residual ground noise, we recommend using twisted pair cable or short cable lengths in this type of configuration. -
Page 14: Operation
The input sensitivity, for each channel, can be adjusted individually using the level controls on the front panel. The level controls on the P1000 are configured to allow each channel to be fully attenuated and are marked from 0 (minimum output) to 10 (full output). -
Page 15: Nomad Safe Area Protection
This multiplication method has numerous problems, including temperature sensitivity, nonlinearity and complexity. The NOMAD circuit, used in the P1000, avoids these problems by deriving the device dissipation by a different method. Sensing circuits measure the device voltage and current. NOMAD determines the allowed current after an established duration. -

Page 18: Field Service Considerations
FIELD SERVICE CONSIDERATIONS A primary focus during the design and development of the P1000 was to ensure the dependability of the amplifiers. The use of MOSFET output transistors and the low voltage trans• ana input stage combined with careful component selection for the circuit assembly made the reliability goals achievable. -

Page 23: Circuit Operation
The transistor Q1 is configured to operate as a switch which controls the constant current source, Q6, of the input differential amp, Q4 and Q5. When Q1 is off the emitter voltage is low turning off Q6. Timing of the Soft Start function is controlled by the charging time of C29 through R13. - Page 24 NOMAD (NOn-Multiplying Advance Decision) Stage Current R67 (R68) Gate Voltage Clamp Reference Voltage Dissipation Threshold Q17 (Q16) Q11 (Q13) Sense Q10 (Q12) Stage Voltage R43 (R54) Maximum power delivery, within the output MOSFET ratings for power, voltage and current, is ensured by our NOMAD (NOn-Multiplying Advance Decision, patent pending) circuit.
- Page 25 Thermal Protection Temp Comparator TS1, R25 The thermal protection is activated, and shuts down audio operation, when the amplifier heatsink reaches an excessively high temperature. The voltage divider R22 and R23 establishes the reference voltage on pin 5 of U5B. The control voltage, on pin 4 is established by the voltage divider TS1 and R25.
